Title: Method for decreasing leakage current of photodiode
Inventor: YANG SHENG-HSIUNG
IPC: H01L27/146
Filed: 2001-05-31
Granted: 2002-04-11
Abstract: The present invention provides a kind of method for decreasing leakage current of photo diode on a semiconductor wafer. The semiconductor wafer surface contains the followings: a P-type substrate; a photo-sensing region, which is used as the photosensitive region of the photo diode; and at least one shallow trench, which is installed in the substrate to surround the periphery of the photosensitive region. For the invented method, a doped polysilicon layer containing P-type dopant is first formed inside the shallow trench. Then, P-type dopant inside the doped polysilicon layer is diffused to the bottom portion of shallow trench and in the P-type substrate of sidewall periphery so as to form a P-type doped region. After that, the doped polysilicon layer is removed and insulating material is used to fill in the shallow trench so as to form the shallow trench isolation. Finally, an N-type doped region is formed at the photosensitive region and is used as the photo-sensing region of the photo diode, in which P-type doped region is used to weaken the electric field of the periphery of the photosensitive region.

Inventor: CHOU BRUCE C S
IPC: H01L31/00

Granted: 2003-02-11
Abstract: The present invention provides an universal micro-mirror design and fabrication in association with wafer bonding technology for use as optically tunable devices, which comprises a micro-Fabry-Perot (FP) tunable filter, a tunable vertical cavity surface emitting laser and an optically tunable receiver. According to the principle of FP interferometer, the optically tunable device comprises: a first substrate having the first surface and the second surface; a first mirror formed on the first surface of the first substrate or the first substrate; a second substrate having the first surface and the second surface; a second mirror fabricated on a hanging mechanical structure which is supported and fixed onto the first surface of the second substrate by at least a supporting point; a first air gap formed between the first surface of the first substrate and the second mirror; a second air gap formed between the first surface of the second substrate and the second mirror. When the universal micro-mirror is used as a tunable filter, the first substrate is identical to the second substrate, and the first air gap is identical to the second air gap which functions as a complete FP resonant cavity. When the universal micro-mirror is used as a tunable vertical cavity surface emitting laser and optically tunable receiver, the first substrate is bonded onto the second substrate by metal diffusion, and the first air gap functions as a part of or complete FP resonant cavity. The length of the FP resonant cavity can be varied by shifting the second mirror through the function of electric field, so as to have outputs with different light frequencies. The present invention also provides an integrated voltage-controlled capacitor fabricated between the hanging mechanical structure and the second substrate to sense the length variation of the FP resonant cavity, so as to control outputs with different light frequencies. At the same time, by anisotropically etching the second substrate to form V-groove or U-groove, a precision fiber coupling structure can be provided for designing and manufacturing with manufacturing, monitoring and assembling integrated together.

Title: Method to use secure passwords in an unsecure program environment
Inventor: FREEMAN JOSEPH WAYNE
IPC: G06F12/16
Filed: 2001-11-06
Granted: 2003-08-11
Abstract: During power up initialization, security data such as passwords and other sensitive data which are stored in a lockable memory device are read and copied to protected system management interrupt (SMI) memory space, subject to verification by code running in the SMI memory space that the call to write the security data originates with a trusted entity. Once copied to SMI memory space, the security data is erased from regular system memory and the lockable storage device is hard locked (requiring a reset to unlock) against direct access prior to starting the operating system. The copy of the security data within the SMI memory space is invisible to the operating system. However, the operating system may initiate a call to code running in the SMI memory space to check a password entered by the user, with the SMI code returning a ""match"" or ""no match"" indication. The security data may thus be employed after the lockable memory device is hard locked and the operating system is started.

Title: Power converter
Inventor: JANSEN ARIAN M
IPC: H02M3/28
Filed: 2001-11-12
Granted: 2006-07-01
Abstract: The invention is a power converter having a transformer with a primary side winding and a secondary side winding. Both the primary side and the secondary side have switches which are switched on and off alternately. When the primary master switch is switched on, the transformer charges. When the primary master switch is switched off, the intrinsic capacitance of the secondary slave switch discharges generating the zero voltage switching condition for the secondary slave switch. The secondary slave switch is switched on at a time determined in accordance with the waveform generated by the transformer. When the secondary slave switch is switched on, the transformer discharges and ultimately the charge from an output capacitor flows into the transformer as a backflow which charges the transformer. The secondary slave switch is switched off at a time determined in accordance with a current flowing through said secondary switch. The intrinsic capacitance of primary master switch discharges generating the zero voltage switching condition for primary master switch which is then switched on and the cycle repeats.

Granted: 2003-09-21
Abstract: A method can improve the etch resistance of a resist pattern and inhibit contraction due to SEM observations. A wafer substrate (1) with a predetermined resist pattern (2) formed thereon is immersed in a solution (10) of an organic substance (11), whereby the organic substance (11) in the solution (10) is introduced into holes (3) in the resist pattern (2). This improves the etch resistance of the resist pattern (2), since carbon generally contributes to improvements in the etch resistance of a resist film. The introduction of the organic substance (11) into the holes (3) can also inhibit contraction due to electron beam radiation involved in SEM observations.
